I need some help with the limits of the integrals when you work out the marginal pdf of X or Y.
I've got the formulae
for the marginal pdf of X and
for Y
Then there's the question
Random variables X and Y have joint pdf
where A is the region bounded between and
Looking at the solutions, the limits for f(x) are between and and I think I get that one but for f(y) they're between and which I can't figure out. Can anyone help?
